Abstract

Nine germplasm lines selected for root traits (volume, dry weight) along with checks were screened for drought
tolerance in field by imposing drought stress from 30-90 DAS. Genotypes RG 373 and RG 1582 recorded >50g/pl.
seed yield with <30% reduction in seed yield under drought stress along with low (<1.0) drought susceptibility index (DSI). These selected germplasm lines can be used in breeding for rainfed conditions.
